Android 如何获得专辑封面查询歌曲

如何获得“封面歌曲”（因此同一张专辑中的歌曲具有相同的封面）

---

我需要另一个问题吗？我不想查询所有相册，我不知道如何将歌曲连接到相册…

您需要在上面的查询中包含相册id

int albumIdColumn = musicCursor.getColumnIndex
            (MediaStore.Audio.Media.ALBUM_ID);

long albumId = musicCursor.getLong(albumIdColumn);

使用相册id，您可以查询封面的路径，如下所示：

private static String getCoverArtPath(long albumId, Context context) {
    Cursor albumCursor = context.getContentResolver().query(
            MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
            new String[]{MediaStore.Audio.Albums.ALBUM_ART},
            MediaStore.Audio.Albums._ID + " = ?",
            new String[]{Long.toString(albumId)},
            null
    );
    boolean queryResult = albumCursor.moveToFirst();
    String result = null;
    if (queryResult) {
        result = albumCursor.getString(0);
    }
    albumCursor.close();
    return result;
}

private static String getCoverArtPath(long albumId, Context context) {
    Cursor albumCursor = context.getContentResolver().query(
            MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
            new String[]{MediaStore.Audio.Albums.ALBUM_ART},
            MediaStore.Audio.Albums._ID + " = ?",
            new String[]{Long.toString(albumId)},
            null
    );
    boolean queryResult = albumCursor.moveToFirst();
    String result = null;
    if (queryResult) {
        result = albumCursor.getString(0);
    }
    albumCursor.close();
    return result;
}
